This invention appertains to new and useful improvements in illumination, and more particularly to a novel dimmer device for automobile headlights.

The principal object of this invention is to provide a construction whereby parking or dim lights can be dimmed as well as the main headlight bulbs in a simple and inexpensive manner.

Another important object oi the invention is to provide a dimmer for automobile headlights which can be readily installed or demounted when desired.

These and other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:-

Figure 1 represents a iront elevational view of the headlight with the dimmer installed thereon.

Fig. 2 represents a sectional view taken substantially on line 2-2 of Fig. 1.

Fig. 3 represents a horizontal sectional View taken substantially on line 3-3 of Fig. 1.

Fig. 4 represents a perspective view of the main headlight bulb dimmer.

Fig. 5 represents a perspective view of the parking bulb dimmer shield.

Referring to the drawings wherein like parts are designated by like numerals it can be seen in Fig. 2, that the numeral 5 represents the headlight casing, with the usual parabolic reflector 6 mounted therein.

Numeral 7 represents the usual rim for retaining the lens '7' against the outer side of the casing 5 and abutting the reflector 6 in the manner clearly shown.

In carrying out the present invention, a longitudinally curved plate 8 is provided, the same tapering rearwardly to terminate in a depending yoke 9. This tapering formation of the plate 8 is to permit snug engagement of the edge portions of the plate with the inner side of the reflector 6 as in the manner clearly shown in Fig. 3.

As is apparent in Figs. 2 and 4, a semi-circular upstanding plate portion 10 is provided at the forward end of the plate 8 and this plate portion 10 is provided with a circular opening 11 therein, while at the edge of this plate portion 10 are the rearwardly extending lugs 12 which are engageable with the reflector 6 as in the manner substantially shown in Fig. 3.

The forward edge of the reflector 6 is notched to receive the lugs 12, so that there is no likelihood of the plate 8 and plate 10 slipping sidewise in the reflector 6.

Due to the curvature of the plate 8 and the fact tion in the reflector.

(Cl. Z140-48.2)

that the under side thereof is highly polished, rays from the main bulb 13, will be reflected onto the ground, there not being any way in which light rays can deflect upwardly to blind oncoming motorists.

If the particular headlight construction is provided with a parking light bulb 14, then the opening 11 is to be provided in the plate 10, otherwise, the opening 11 is not provided.

When the opening 11 is provided to permit rays 65 from the bulb 14 to pass therethrough, a semicircular-shaped shield 15 is provided and equipped with lugs 16 at its ends and intermediate portion. The intermediate portion of this shield 15 is bulged forwardly and preferably polished 70 on its inner side to provide a reflecting surface. Thus light rays from the bulb 14 will be deflected downwardly, and there will be no chance that rays from this parking light will cause accidents by temporarily blinding approaching motorists.

The lugs 16 engage over the upper portion of the lens 7 A'as in the manner shown in Fig. 2,

while the rim 7 otherwise engages the shield 15 to prevent forward displacement.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having thus described my invention what I claim as new is:-

The herein described headlight consisting essentially of a casing, a reflector in the casing, a lens, a rim securing the lens against the forward ends of the casing and reflector, a main headlight bulb disposed in the reflector, a parking light bulb disposed in the reflector and in a horizontal plane above that of the main headlight bulb, a longitudinally curved reflector plate disposed in the reflector above the main headlight bulb and below the parking light bulb and lhaving at its rear end a yoke engaging the socket of the main headlight bulb and also having at its forward end an upstanding plate portion shaped to conform with the curvature of the forward portion of the reflector, said upstanding plate portion having an' opening in line with the parking light bulb, and the said reflector having notches in its forward edge, and the said upstanding plate portion having at intervals rearwardly extending lugs disposed in the said notches of the reflector whereby the reflector plate is held against lateral deflec- GEORGE J.
